To all whom it may concern;

Be it known that I, JENKIN Wi'LLIAMs, a citizen of the United States of \America,

residing at Pittsburgh, in thecounty of Alle- 'gheny and State ofPennsylvania, have invented a certain new; and useful Improvement in Guide-Rest Bars. for Rolling-Mills,

specification.

of which .i-mprove'mepltfl the following a guide-rest bars-used in connection with mills for rolling plates or. bars of metal, and it is particularly applicable to plate mills.

The -said invention consists in the peculiar construction of saidguide rest bars, and the disposition or arrangement of the same with relation 'to the rolls, and bf means whereby the said-guide rest bars may be adjusted as a whole, toward orawa-y from the roll or rolls and may be given any desired angle of inclination with relation to the rollor rolls,

and held'rigid and free from contact with the rolls, thereby preventing'whatis known in the art as burring or the gradual turning up of the edges of the guide rest bar ber of separate pieces, which were secured upon the rest bar and were separately adjusted with relation to the roll or rolls, and

so arranged that'the inner ends of the guides or guide platesrested upon the roll, the result of this arrangementwas that the ends of the guide plate soresting on the,r0ll-became by constant wean-turned or stoved up so as to form an irregular cutting edge,

which not only damaged the plates passing through the rolls but at times offered suificient resistance to' said plate as to cause breakage of the rest bars, and at times even of the roll itself;

The object'of this invention isto avoid these difliculties, and to this purpose I ,pro

'duce a one piece guide rest bar, so disposed or arranged with-relation to the roll that the inner edge adjacentto the roll is ke'ptout of contact with the roll, yet very close there-' to, and capable of being adjusted toward or away fromthe'roll as .a whole. I .accomplish these objects by the device hereinafter 1 more fully described, reference being had to the accompanying dravvingaf nm part hereof, in WlIICh I; Figure 1 is an end elevation of a set of ordmary three high rolls, sti ches are ..commonly used in mills for the manufacture rolls. Fig. 3 is an enlarged side elevation, of one of the bearing blocks forsupporting 1 themiddle roll, showing the manner in which one end of the guide rest bars is sup.- por'ted and adjusted-to the proper position with reference to said roll. Fig.4; is a plan view of the sameu Fig, 5 shows a modified 4 form of said support. Inpracticing my invention, a set of rolls may "be used, consisting of three. rolls, one

arranged abovethe other, and. mounted in housings l, the upper roll 2 being of the same diameter as the lowerroll 4, and the middle roll 3 being of'less diamete'r,.and beare slidably mounted in the housings in such manner-as to permit the plate or bar 18, to

be passed between-the-upper roll 2 and the middle roll 3 and the lowerroll 4 and the said middle roll. Upon the in'ner faces of these bearing blocks 5, are formed or secured pockets 6, substantially U shaped, the upper ends being open, the, ribs forming ysaid pocketsprojecting from said blocks at right angles thereto, and having flat inner face These pockets 6 are arranged at the sides, respectively, of the middle roll 3 and are used as supports for the receiving guide rest bar '10, and the delivery guide'rest bar 10, respectively,-

The guide rest bar 10 comprises a fiat top 'or guide surface, and a nose portion comprising-a series of webs 11', pro}ect1ng downwardlyand terminating inya curved point 17 on a line at'or' slightly below a line drawn transversely through the center-of the middlei rol-l, -f0r;'the purpose of preventing the end' of the plate-'01" bar passing between the 1 lower rolls and the middle roll curving up- 'ward-around said middle roll,- and an inte-- gral supporting portion 13-; and is provided; with bearings or wings 13 at the ends thereof, which are suitably'secured in the said pockets 6 The said guide rest bar-is its, located onwthe receivingrside of i'nill at the passbetween-the middle and-upper.v rolls. The guide rest :bar -1 located at the de- 75 ing supported in carrying blocks 5, which 1 livery side ofthe'mill, i. ,e., at the pass be-fl tween the middleand upper 'roll and the middle".z'tnd lower roll, as shown Fig. 1,

sired-angle of' inclination with relation totlie'rolladjacent'thereto, and capable of be ing,'adjusted from and toward the roll by i wdges are held in position by means of the (ends of the bolts 9.

The curved adjacent to the roll are each, rovided'w-ith. .a recess 12, in which, if desire ,jawater supp y pipe 15 may be secured by-meansofithe comprises a flat top anda series of transverse webs; 11,- constituting the nose portionwhich projects toward the roll adjacent thereto and into-close proximity but out ofcontact therewith, (in practice the requisite distance has been "shown to be about one- 'sixteenth of an inch from the face'of the ,roll, and also a little below the upper 'face of the same) and is provided-with bearingsor wings 13, which are capable of being secured in bearings formed ln the hous-- ings, 1. The bearings 13 are provided with rounded bases l ladapted'torest' upon the bottom-curve of-the pockets 6,".whereby the said guide rest bars may be given any deliners 8 '(Figs. .1 and These -liners or caps 7, which are secured to theupper open pockets 6, means v of .the

faces the guide' 'i'est' bars starved ends of the bolts 16.

- horizontal rolls 'mounted'in'said housings,

In Fig. 5 of he drawings, I have shown a slight modification of the form of. the pockets 6, in which the'sidewalls of the same are not parallel the onewith the other,

andin which wedge shaped liners are used to adjust the guide rest bars.

Having described my invention, what I claim and desire to secure by Letters Pat-.

cut is I ljA rolling mill comprising. housings, horizontal' rolls mounted in said housings, and a guide-rest bar at the front erdelivery side of said mill adjustable as a whole to.-

ward and away from one of the rolls, the

edge of said guide-rest bar adjacent to the roll, extending along and in close. prox-,' imity but out of contact with the roll, and

means for holding said guide rest bar'in its adjusted position;

2. A rolling mill comprising housings,

but out of contact therewith, and means for the mill adjustable as a whole to- 3. In a rolling mill',-the combination of a' set ofhorizontal rolls, supporting members for therolls, guide-rest bars arranged at-the delivery and receiving sides'of the mill, 're-.

spectively, and adjustable as a whole ,to-

,wardor away from one of the rolls, the.

edge of said guide-rest bars adjacent to said rolls-forming the guide part thereof,

and extending along and projecting toward theroll into close proximity to the surface but out of contact therewith, and means for holding the guide rest; bars in the desired adjusted positiom.-.

4. .A; rolling mill comprising a stand of horizontal-rolls mounted in bearings carried' fin;housings',* and a guide rest-bar arranged at the front or delivery. side of the *mill adjustable as a whole toward anda'way from --one off the rolls, said guide-rest. bar

having a; nose portion forming theguide part thereofextending along and projecting toward the you mounted in said-bearings,

said guide-rest bar having end wings, the bearings having slots wider. thantheend wings, and arranged to receive, the wings, and liners arrangedjto hold the bar inits adjusted position. a 1 5;:In a rollingmill, thecombination of a set ofhorizontal rolls, supporting bearguide rest ings for theroll s, guide-rest bars arranged at the deliveryand-receivin sides of the mill, respectively, and adjusta le as a whole toward' and away from one of therolls, the
